IMPROVEMENT IN HERNIAL TRUSSES.

Specification forming part of Letters Patent No. 54,521, dated May 8,1866.

To all whom it may concern:

Be it known that I, ADOLPII O. FoIisBERG, oi' Gincin nati, Hamiltoncounty, Ohio, have invented a new and useful Improvement in the Pad forI-Iernia-I'russes5 and I do hereby declare the following to be a i'ull,clear, and cxactdescription ot'm y invention, reference being had to theaccompanying drawings, making part of this specification.

This invention relates` to an arrangement and construction of the padfor the cure or aileviation of inguinal hernia, which insures greatereffectiveness in supporting and pressing back the protruding mass and insecuring the reunion or' the severed parts.

Figure l is a perspective view of a truss emf bodying my invention. Fig.2 is a longitudinal section through the pad.

I make of the customary or any improved form the following parts, towit, the mainspring A, back-pad B, strap C, button D, and

i arms E E', for attachmentot' my hernia pad,

which pad I construct as follows: Attached to the arms E E is an ovalback, F, having a perforated marginal depression or channel, j', for thereception and attachment oi' a cushion, which constitutes my annular orexterior pad, G. Hinged to the back F is my central pad, H, having theform of one-half an egg, the larger part downward. Tapped within theback F is a set-screw, I, which, bearing against the rear side of thepad H, enables the large end to be set more out or in, as the nature ofeach particular case may require. Thus when the hernia is severe andprotuberant the butt or large end of the pad H is set outward or ftoward the personof the wearer, so as to support and press backward theprotrusion, which having been effected, the screw may be graduallyrelaxed and the pad H restored to a more vertical position.

B y forming the lower end ofthe pad H larger and more prominent than theupper part a more griping action is obtained upon the upper part of theinguinal canal, acting to close the oriiice and to restore and retainthe bowels to the natural cavity of the abdomen. At the same time theirritation acts to enlarge and strengthen the confining-muscles..

I have selected as the preferred type of my invention a form whichnumerous practical tests have proved to be effective, but do not desireto restrict the invention to the i precise construction represented solong as the essential objects of an upward and inward pressure aresecured by means substantially equivalent. For example, the central pad,H, may approximate a hemispheroidal form, and a spring may be employedto holdthe pad H snugly against the screw.

Iclaim herein as new and of my invention- The hinged pad H, having apositive and nou-elastic adjustment, substantially as described.

In testimony of which invention I hereunto set my hand.

A. O. FORSBERG.
